“…The water retention capacity (𝑤 ) was determined as the difference between the amount of water added to the funnel and the amount of water collected in the cylinder after 72 h. The experimental setup was constructed in the form of cylindrical columns using transparent PVC materials, 100 mm in diameter, to create economical and compact samples with a diameter that would limit the potential edge effect and dispersion in the columns [63]. Typical rain garden designs typically use a mixture of 10-15% gravel by volume, 50% construction or river sand, 20-30% topsoil, and 20-30% mulch [64]. The bulk layers in our samples (in the sequence from top to bottom) were as follows: 330 mm of soil, 330 mm of sand, and 180 mm of gravel.…”

Rain gardens are used to solve urban problems related to the negative impact of stormwater. (1) Scientific contributions from different countries provide general guidelines for the design and operation of rain gardens in different geographical areas. Given the small spatial scale of rain gardens, the use of existing infiltration models often leads to design errors. (2) The purpose of this paper is to develop a hydrological model by introducing a system of equations that extends the ability to calculate the rate, flow rate and time of saturation of layers with moisture and rainwater leakage from the rain garden system. (3) The results obtained allow us to describe the dynamic processes of passage and saturation of layers of the rain garden at a certain point in time, which extends the ability to calculate the flow rate. It was established that the smaller the area of the rain garden compared to the area of the catchment basin, the faster it reaches its full saturation. Increasing the thickness of the rain garden layers allows for an increase in the efficiency of water retention at a lower value of the area ratio. (4) The practical significance of the results obtained is especially important for the correct description of hydrodynamics in the system and determining the optimal conditions for the effective functioning and management of the rain garden structure for any climatic region.

“…Many other physicochemical parameters are decisive; for example, many freshwater organisms, such as fish and amphibians cannot survive at a salinity higher than 3 grams of salt per liter of water (Davis & McCuen, 2005). Moreover, other toxic effects on living beings at a certain dose of polluting substances have a toxic effect on living beings.…”

“…In summer, rivers have limited water flow thus allowing suspended solids as large as sand to settle throughout the water column (Fondriest, 2016). Settled solids further block water flow and limit solar radiation for microorganisms (Davis & McCuen, 2005). In contrast, TSS measurement increases in the presence of storm water runoff (Sosiak, 2001).…”

“…Turbidity is a measure of how suspended particles influence the clarity of water, and it is often measured in Nephelometric Turbidity Units (NTU) (Stone et al, 2016). It is also used as indicator of TSS and degree of erosion (Davis & McCuen, 2005). Increase in turbidity can increase water temperature as it absorbs more radiance from the sun and a warmer water tends to hold lesser amount of dissolved oxygen (DO) (Davis & McCuen, 2005;Fondriest, 2016).…”

Remote sensing of land use changes and impacts on river turbidity in a small-scale mining region

The effective management of artisanal and small-scale mining (ASM) on regional and national scales must be based on good understanding of land and water footprints from various land use and land covers. The diffuse, dynamic and often remote nature of ASM means that traditional ground-based surveys are likely to be impractical except for local scale studies. Remote sensing offers a low-cost option for surveying land use changes and water turbidity, and quantifying the impact of ASM on water quality. However, there are questions about the reliability of remote sensing products for these tasks, and there is a need for recommendations about suitable products, data resolutions and analysis techniques. A case study of the Addalam river basin in the Cagayan region, situated in Luzon forming a part of the Philippine archipelago, was used to address these research questions. The value of alternative satellite products was tested using independent sources of land use, suspended sediments and turbidity data from project partners OceanaGold (Philippines), International RiverFoundation, and local government agencies. The unpredictable climate in wet tropical regions, and the spatial limitations of current satellite imageries are the challenges for remote detection of ASM. Pleiades and SPOT imageries were identified as potentially suitable and were tested. Historical spatial data on location and type of ASM mines were collected from the field, and were utilised as training data for classification through the OB-SVM classifier. The analysis resulted in overall accuracy between 87% and 89% for three different images; Pleiades-1A HiRI sensor for the 2013 and 2014 images, and SPOT-6 NAOMI sensor for the 2016 image. The main land use features, particularly the Didipio large-scale mine, were well identified by the OB-SVM classifier; however, the presence of small-scale mines was slightly under identified. The lack of consistency in their shape, and their small scale compared to the pixel sizes, meant they could not be reliably distinguished from other land clearance types. The biasedadjusted surface areas were acquired to determine the best possible estimates of the area variation in small-scale mines throughout the year. The image analysis indicated an increase in small-scale mining area from 91,000 m 2 or 0.2% in March 2013 to 121,000 m 2 or 0.3% in May 2014, and then a decrease to 39,000 m 2 or 0.1% in January 2016. Various land use features in a mining region have different sediment yields, which have significant influence on the concentration of suspended solids in rivers. In-situ sampling can only describe the integrated impact of the upstream land uses. A model of total suspended solids (TSS) through the acquired surface reflectance from calibrated satellite images can be used to assess the fate and transport of sediments throughout the catchment of Didipio.
