Impacts of Land Use and Climate Changes on Hydrological Processes in South Dakota Watersheds
… The first aspect consists of characterizing hydrological changes between two recent decades in three representative watersheds – Bad River watershed, Skunk Creek watershed and Upper Big Sioux River watershed. Two historical land use maps (NLCD 1992 and 2011) were used to represent land use …

Hillslope and watershed scale hydrological processes and grazing management in a Dartmoor catchment, Southwest England
Concerns have been raised on the deterioration of heather moorland due to management in the UK. A study was therefore conducted on the impacts of moorland management on the soils and hydrology of a catchment on Dartmoor. Soil moisture was measured gridwise using TDR on 19 occasions. At 23 sites …

Hydrological processes in volcanic ash soils : measuring, modelling and understanding runoff generation in an undisturbed catchment
… environments are controlled by runoff generation processes in the basin upstream. Runoff generation processes are thus a major control of the terrestrial part of the water cycle, influencing both, water quality and water quantity as well as their dynamics. The understanding of these processes …

Integrated Modeling and Optimization of Stormwater Control Measures for Sustainable Watershed Management Under Urbanization and Changing Rainfall Patterns
… and climate change (CC) are altering the natural hydrological cycle, contributing to more frequent and severe flooding. These changes are particularly pronounced in mixed urban–rural watersheds, where diverse land uses complicate hydrologic modeling and stormwater planning. To improve resilience …
