Geomorphic histories for river and catchment management.

River and catchment management usually proceeds from the identification of an undesirable state (e.g. pollution, sedimentation, excessive water extraction, dams, invasion by exotic species) to a strategy for reaching a desirable state described as a target. Desirable states are usually determined from community values, economic assessments and ecosystem functions, or a combination of these. Whe...

Application of Geomorphic River Recovery in river management, case study, Northen Alborz, Lavij Rud catchment

Rivers have a complicated and various condition in the diverse environment, and various science such as Hydrology, geomorphology, hydraulic, ecology and engineering have it been discussed. River geomorphology with studying of river process and landforms, examination of river landscape evolution, can be playing an important role in identifying of river channel character and behavior. To order th...

Parsimonious Catchment and River Flow Modelling

It is increasingly the case that models are being developed as “evolving” products rather than one-off application tools, such that auditable modelling versus ad hoc treatment of models becomes a pivotal issue. Auditable modelling is particularly vital to “parsimonious modelling” aimed at meeting specific modelling requirements. This paper outlines various contributory factors and aims to seed ...

An integrated water resources management approach for the River Spree and its catchment.

In this paper a concept of an integrated water quality model for a river catchment area is presented. The main focus is directed to the development of a water quality module for rivers. Necessary simplifications for calculation of hydraulics and water quality will be explained. Furthermore, by first simulation results possible applications of the model are presented.
