Predicting location and length of ephemeral gullies with a process-based Topographic Index model [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Ephemeral gully (EG) erosion can be a major source of sediment in agricultural watersheds and predicting the location and length of EGs is important to assess sediment source areas. Topographic index (TI) models utilize topographic-only factors to locate

International Soil and Water Conservation Research, 2021 Evaluation of prediction models is crucial to achieving valid information on erosion processes and their management choices. WEPP model efficiency in predicting ephemeral gully (EG) erosion was recently tested and compared with both EGEM and empirical ...

Environmental Laws in Nigeria and Occurrence of Some Geohazards: A Review [PDF]
, 2017 Nigeria as a country is blessed with an abundance of both human and natural resources. Exploitation of natural resources in Nigeria over the years with little or no regard for the environment has increased susceptibility of parts of the country to ...

Evaluating ephemeral gullies with a process-based topographic index model [PDF]
, 2014 Soil conservation practices have been implemented to control soil degradation from sheet and rill erosion, but excessive sediment runoff remains among the most prevalent water quality problems in the world.

Combining bulk sediment OSL and meteoric 10 Be fingerprinting techniques to identify gully initiation sites and erosion depths [PDF]
, 2017 Deep erosional gullies dissect landscapes around the world. Existing erosion models focus on predicting where gullies might begin to erode, but identifying where existing gullies were initiated and under what conditions is difficult, especially when ...

Quantifying uncertainty in high-resolution remotely sensed topographic surveys for ephemeral gully channel monitoring [PDF]
Earth Surface Dynamics, 2017 Spatio-temporal measurements of landform evolution provide the basis for process-based theory formulation and validation. Over time, field measurements of landforms have increased significantly worldwide, driven primarily by the availability of new ...

Spatial modelling of ephemeral gully incision: a combined empirical and physical approach.
, 2006 In 1998 and 1999, several ephemeral gullies were monitored in the Ganspoel catchment near Leuven (Belgium). In this study, a modelling framework to simulate the incision and formation of ephemeral gullies is proposed and tested with the gullies measured in Belgium.
