Modeling the impact of measured and projected climate and management systems on agricultural fields: Surface runoff, soil moisture, and soil erosion. [PDF]

J Environ Qual
Abstract As global climate change poses a challenge to crop production, it is imperative to prioritize effective adaptation of agricultural systems based on a scientific understanding of likely impacts. In this study, we applied an integrated watershed modeling framework to examine the impacts of projected climate on runoff, soil moisture, and soil ...

Impacts of Land‐Use Change on the Hydrology of Lake Tana Basin, Upper Blue Nile River Basin, Ethiopia

Global Challenges, Volume 6, Issue 8, August 2022., 2022
The soil and water assessment tool (SWAT) model is used to assess the effects of land‐use change on the hydrological processes of the Lake Tana basin. According to the findings, the SWAT model is essential for effective modeling of the impact of land‐use change on water quality and quantity. Abstract Human activities impact hydrology through changes in

A parametric sensitivity analysis for prioritizing regolith knowledge needs for modeling water transfers in the West African critical zone

Vadose Zone Journal, Volume 20, Issue 6, November/December 2021., 2021
Abstract Hard rock aquifers (HRAs) in West Africa (WA) are located within a thick regolith layer. The representation of thick tropical regolith in integrated hydrological models lacks consensus on aquifer geometries and parameter ranges. Our main objective was to determine the knowledge requirements on saturated hydraulic conductivity (Ks) to model the

Forest regeneration can positively contribute to local hydrological ecosystem services: Implications for forest landscape restoration

Journal of Applied Ecology, Volume 58, Issue 4, Page 755-765, April 2021., 2021
Encouraging natural regeneration is increasingly seen as a cost‐effective way to deliver forest landscape restoration. Our data suggest that increasing the abundance of young secondary forest in the tropics, by increasing fallow lengths in the shifting cultivation cycle, could make a positive contribution to locally important hydrological ecosystem ...

Hydrologie et dynamique hydroécologique des cours d'eau [PDF]

, 1992
La dynamique écologique des cours d'eau est fortement liée à leur régime hydrologique qui en façonne la structure morphologique à l'occasion de crues caractéristiques mais qui en rythme également l'habitat physique quotidien.

Improved Understanding of the Link Between Catchment‐Scale Vegetation Accessible Storage and Satellite‐Derived Soil Water Index

Water Resources Research, Volume 56, Issue 3, March 2020., 2020
Abstract The spatiotemporal dynamics of water volumes stored in the unsaturated root zone are a key control on the response of terrestrial hydrological systems. Robust, catchment‐scale root‐zone soil moisture estimates are thus critical for reliable predictions of river flow, groundwater recharge, or evaporation.
