“…S2). Recent increases in precipitation and streamflows have been reported across the region during the last few decades (Foufoula-Georgiou et al, 2015;Frans et al, 2013;Gerbert and Krug, 1996;Groisman et al, 2001;Juckem et al, 2008;Novotny and Stefan, 2007;Schottler et al, 2014). Settlement, agricultural intensification, and development differ in timing and intensity among basins, but are generally similar.…”

“…Using multiple gauges for a single basin, we compiled seven annual flow metrics: mean annual flow, 7-day average annual low flow winter (November-April), 7-day average annual low flow summer (May-October), peak mean daily flow spring (March-May), peak mean daily flow summer and fall (June-November), high flow days, and extreme flow days using mean daily flow data from USGS gauges within each basin ( Fig. S2; Table 1) following the methods of Novotny and Stefan (2007). The number of high and extreme flow days refers to the number of days in a given year that are 1 and 2 standard deviations above the 1950-2010 mean.…”

Abstract. Complete transformations of land cover from prairie, wetlands, and hardwood forests to row crop agriculture and urban centers are thought to have caused profound changes in hydrology in the Upper Midwestern US since the 1800s. In this study, we investigate four large (23 000-69 000 km 2 ) Midwest river basins that span climate and land use gradients to understand how climate and agricultural drainage have influenced basin hydrology over the last 79 years. We use daily, monthly, and annual flow metrics to document streamflow changes and discuss those changes in the context of precipitation and land use changes. Since 1935, flow, precipitation, artificial drainage extent, and corn and soybean acreage have increased across the region. In extensively drained basins, we observe 2 to 4 fold increases in low flows and 1.5 to 3 fold increases in high and extreme flows. Using a water budget, we determined that the storage term has decreased in intensively drained and cultivated basins by 30-200 % since 1975, but increased by roughly 30 % in the less agricultural basin. Storage has generally decreased during spring and summer months and increased during fall and winter months in all watersheds. Thus, the loss of storage and enhanced hydrologic connectivity and efficiency imparted by artificial agricultural drainage appear to have amplified the streamflow response to precipitation increases in the Midwest. Future increases in precipitation are likely to further intensify drainage practices and increase streamflows. Increased streamflow has implications for flood risk, channel adjustment, and sediment and nutrient transport and presents unique challenges for agriculture and water resource management in the Midwest. Better documentation of existing and future drain tile and ditch installation is needed to further understand the role of climate versus drainage across multiple spatial and temporal scales.

“…The study area, which drains about 1.5 km 2 , is mostly vegetated. In summer the riparian area of the ditch typically gets invaded by tall big bluestem (Andropogon gerardii), indian grass (Sorghastrum), and switchgrass (Panicum virgatum) with a mean height of 1.3 m. The area drained by the ditch is highly agricultural and dominated by very poorly (71%) to poorly drained (18%) soils with an average slope less than 0.6% [35]. Corn-soybean rotation under no-till row crop is mainly practiced in the drained area of the ditch.…”

Extensive network of tile drains present in the Midwest USA accelerate losses of nutrients to receiving ditches, rivers and eventually to the Gulf of Mexico. Nutrient inputs from agricultural watersheds and their role in affecting water quality have received increased attention recently; however, benthic sediment-nutrient interactions in tile-fed drainage ditches is still a matter of active research in consideration to nutrient discharge from tile drains. In this study, phosphorus (P) and nitrogen (N) contents and variability of nutrient retention ability of benthic sediments upstream and downstream from tile drain outlets were evaluated in managed agricultural drainage ditches in Indiana. Sediment samples were collected every three months upstream and downstream from selected tile drains in three ditches in northwest Indiana. Sediment equilibrium P concentrations (EPC0) were measured to examine P adsorption-desorption and equilibrium characteristics of benthic sediments in the ditches. P sorption index (PSI), exchangeable P (ExP), and exchangeable NH 4 + -N (ExN) were measured to evaluate nutrient retention ability and readily available nutrient content of benthic sediments. Results indicated a dynamic interaction between benthic sediment and overlying water column where sediments were acting as a sink or a source of P. There were no differences in nutrient retention ability between sediments collected upstream and sediments collected downstream from the selected tile drains. While the data, except for ExN, was comparable to reported values by previous studies in Indiana's drainage ditches, there was no particular seasonal pattern in the content of exchangeable nutrient content in sediments at all three sites. This study also OPEN ACCESSWater 2010, 2 412 suggested that nutrient uptake by benthic sediments in these drainage ditches is not always efficient; therefore watershed management should focus on minimizing the delivery of nutrients into ditches while maintaining their drainage functionality.

“…The main benefit of utilizing data obtained by RS methods (Lipský 1990;Naz 2009) is the ability to document the unequivocal link between DS presence in LP and the negative manifestations due to their altered/reduced functionality requiring repairs, i.e., the removal of the cause of waterlogging. Based on these data, soil-protective technologies, or anti-erosive measures, should also include technical measures aimed at repairing DS defects, thus removing the causes underlying the negative waterlogging, potential erosion, and varying degrees of pedological characteristic deterioration in LP.…”

Subsurface drainage systems are among the most important meliorative measures taken in the Czech Republic. Nevertheless, their functions are perceived rather differently by Czech society. Perspectives differ among landowners, farmers, water managers, and environmentalists. With changing climatic conditions and new agricultural practices, the conditions of the existing drainage systems must be reassessed, particularly in relation to future strategy for funding and management. In this regard, the main decision makers in the Czech Republic are the farmers, rather than the state or landowners who would probably be more suitable. This paper presents the results of a survey of the conditions of drainage systems, their maintenance and their defects. New technologies, mainly remote sensing, and their use for the identification and survey of drainage systems are also presented. Land drainage measures have changed the entire landscape in the Czech Republic (agricultural intensification has caused the loss of a number of natural habitats and natural water flows). In the context of increasingly common occurrences of hydrological extremes and the aging of the drainage systems, the existence of such systems must be reconsidered. Either they should be preserved for agricultural production purposes, or, on the contrary, gradually eliminated to promote the recovery of natural habitats. The best solution for each part of the Czech Republic will differ according to the landscape characteristics of the given area. Key words: amelioration, survey flight, phytoindicationAbstrakt: Drenážní odvodnění je v podmínkách ČR plošně velmi významným melioračním opatřením. Jeho funkce jsou ve společnosti vnímány diametrálně odlišně. Rozlišujeme pohled vlastníka pozemku, hospodařícího zemědělce, správce vodního díla nebo ekologa. Tak, jak se mění zemědělství i klimatické podmínky, je nutné posoudit I změněné podmínky ve vztahu k existujícímu odvodnění. S tím souvisí i další strategie jejich podpory a správy. Dominantní roli v ČR v tomto ohledu sehrává uživatel pozemku, nikoli stát nebo vlastník, jak by bylo zřejmě správné. V příspěvku jsou dokumentovány výsledky provedených šetření k popisu stavu drenáží, způsobů jejich údržby, četnosti výskytu závad a možnosti využití moderních technologií a metod DPZ pro jejich identifikaci i pro analýzu odvodněného území v širších souvislostech. Výstavba odvodnění zásadně změnila ráz české krajiny. Podpořila intenzifikaci zemědělství, a tím i úbytek řady přírodních stanovišť a přirozených vodních toků. Zvyšování extremity hydrologických jevů a stárnutí těchto vodohospodářských děl zvyšuje naléhavost řešení jejich další existence v různých částech ČR: zachování pro zemědělskou produkci i postupný útlum až likvidaci pro obnovu přirozených stanovišť.
