Assessing the impacts of flow diversion terraces on stream water and sediment yields at a watershed level using SWAT model

Simulating cold-region hydrology in an intensively drained agricultural watershed in Manitoba, Canada, using the Cold Regions Hydrological Model

“…The interaction between agricultural management and the hydrology of cold regions remains a topic of ongoing research (Rahman et al, 2014;King et al, 2015) given the need for improved understanding of processes such as prevalence of preferential flowpaths, enhanced hydrological connectivity promoted by drainage, and impact of different cropping systems on runoff generation. Hydrological models have been utilized at varying spatial scales to model the hydrology of agricultural areas of cold-climate countries such as Finland (Grizzetti et al, 2003;Knisel and Turtola, 2000), Russia (Schierhorn et al, 2014a, b), and Canada (Yang et al, 2014(Yang et al, , 2009). Overall, little research addressing specificities of agriculture in cold-region hydrology is available in the literature, although this activity is quite relevant in northern latitude regions such as the northern Great Plains (North America; Desaulniers and Gritzner, 2006;Wishart, 2004;Sharp, 1952;Li et al, 2010), northwestern Europe (Scandinavia; Parry et al, 1988), and northern Asia (Wang et al, 2002;Blanke et al, 2007).…”

Hydrology and water quality across gradients of agricultural intensity in the Little River watershed area, New Brunswick, Canada

“…During the growing season, many factors like cropping system, hilling, fertilizer application, crop canopy development, land management practices (BMPs), and watershed size could significantly influence the discharges as reported in previous research (Yang et al 2009). For example, hilling up-down slope in potato production could increase discharge, while hilling along contour lines could potentially reduce discharge.…”

“…Although the watershed is relatively large and could potentially buffer the inputs from the BBW and ULRW, the farmland area (4.3 times the entire size of the BBW) likely coupled sediment yield to rainfall. In contrast, sediment concentration in the BBW may be affected by the high percentage of land with conservation systems (Yang et al 2009), and in the ULRW, may be due to the interception of rainfall by the forest canopy, which can reduce the energy of rainfall impact.…”

“…These conservation practices in the BBW reduced carrying capacity of runoff to transport sediment. With a wellcalibrated Soil and Water Assessment Tool model, Yang et al (2009) ), which represented a reduction of 20%.…”

Conservation management practices: Success story of the Hog Creek and Sturgeon River watersheds, Ontario, Canada

“…Monitoring is always a better and preferred option, but it is an expensive and time-consuming method and yields only site-specific results for a given set of climatic conditions. Models can be used to evaluate the impacts of BMPs on water quality under scenarios that would be difficult, if not impossible, to study experimentally (Bracmort et al 2006;Lin et al 2009;O'Connor and Rossi 2009;Yang et al 2009a;Busteed et al 2009;Gazendam et al 2009;Daggupati et al 2011;Yang et al 2012;Dechmi and Skhiri 2013;Liu et al 2015b). …”
