Potential runoff

Runoff reduction is the goal of soil and water conservation in agricultural watersheds. Through the runoff, many substances of soil such as sediment, nutrients have been eroded to end up in streams, rivers, and lakes. In decades, studies have revealed various mitigation, including structure and non–structure conservation ranging from field scale to watershed scale.

This study investigates the impact of climate change (CC) on water resources in Phu Yen province, Vietnam by assessing historical trends of temperature, rainfall and flood simulation scenarios from a report of Vietnam of the Ministry of Natural Resources and Environment in 2020. The method for assessing the impacts on water resources was provided in the report of the Intergovernmental Panel on Climate Change (IPCC) in 2007.

Modeling approach has considered as an effective alternative method for environmental risk assessment in recent decades. This work aimed to assess the pesticide fate and transport from rice paddy which has higher potential of pesticide runoff compared to upland fields as reported in previous studies. The study area was the Sakura River watershed, Ibaraki Prefecture, Japan.

Know the runoff volume for a watershed as runoff is the most important hydrological component for a design of any hydrologic structure and especially in the area of water scarcity (Ibrahim Kaleel et al., 2018). In carrying out water availability studies, it is always appropriate to use the observed runoff data.

The study revealed that structures could retain water up to 273 days, which suggests a great possibility to use harvested surface runoff to improve the catchment's agricultural output if the water can be used wisely.

This paper is about the impact of climate change on water resources, mainly focusing upon the consequences of climate change on Ladakh people based on both qualitative and quantitative approaches. Inadequacy of water resources, irregular rainfall pattern and coping up under such scared water consequences are the major problems in the study area. The main sources of water are glaciers, hand pump, stream and springs.

Morphometric analysis, which refers to the science of quantitative analysis of land surface, has been carried on Kamleshwar watershed of Hiran River in Gujarat using remote sensing and GIS techniques. Digital Elevation Model of 30 m × 30 m resolution was used to prepare the detailed drainage map in ArcGIS software and stream ordering was in which study area has trunk order of 5. Total seventeen morphometric parameters including linear, areal and relief aspects have been estimated. Mean bifurcation ratio of the watershed has been calculated to be 3.

Water scarcity has many negative impacts on the environment, including lakes, rivers, wetlands, and other fresh water resources. Furthermore, water shortage makes flow management in the rehabilitation of village streams problematic. Owing to poor water resource management system and climate change India faces a persistent water shortage. Indian agriculture accounts for 90% water use due to fast track ground water depletion and poor irrigation systems. Water is a critical input into agriculture in nearly all its aspects having a determining effect on the eventual yield.

Water balance components of a bare soil with slope varying from 5% to 30% in Chuncheon, South Korea, were simulated using the E-DiGOR model, which proposed an interactive way to quantify runoff, drainage, soil water storage, and evaporation.

It is important to note that NPDES permits are only required of so-called “point sources.” Point sources tend to be larger industrial and commercial facilities and public treatment facilities. Some large agricultural operations are considered point sources, but, by and large, runoff from farms, roads, lawns, and most small pollution sources are not directly regulated. These “nonpoint sources” are the subject of increased scrutiny, since most of the nation’s remaining water quality problems are due to nonpoint pollution.
