Roaded Catchments To Improve Reliability Of Farm Dams, David Stanton

Bulletins 4000 -

Maintaining reliable on-farm water supplies is an on-going challenge for landholders throughout Western Australia. Improving reliability of dams by constructing a roaded catchment is one of the most cost-effective methods of improving the performance and reliability of a farm water supply.

A roaded catchment is a water-harvesting structure designed to increase the amount of run-off from the catchment above a dam. The 'roads' of a roaded catchment are parallel ridges of earth with batters (or side slopes) that cause run-off to be directed into troughs or channels. The surface is lined with clay and compacted to make it smooth and …

Altered Hydrology In Connecticut Watersheds Prioritized For Protection, Denise Burchsted

Denise Burchsted

The Nature Conservancy (TNC) has selected the Saugatuck, Salmon, Eight Mile, Mount Hope / Natchaug, and Hollenbeck River watersheds for priority protection in Connecticut. A number of threats, including altered hydrology, have been identified in these watersheds. This project has been designed to better understand that threat and provide some context for future protection or restoration of the hydrology within those watersheds. The definition of altered hydrology is problematic, as the time at which the watersheds are considered unaltered is ambiguous and historic data is often unavailable. In order to address that difficulty, this project used the following approach: 1. …
