Altered Hydrology In Connecticut Watersheds Prioritized For Protection, Denise Burchsted Jan 2005

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. …


The Role Of Geomorphic Features And Hydrologic Processes On Sediment Clusters In Gravel-Bed Rivers, Washington: A Field-Based Approach, Ross Richard Hendrick Jan 2005

The Role Of Geomorphic Features And Hydrologic Processes On Sediment Clusters In Gravel-Bed Rivers, Washington: A Field-Based Approach, Ross Richard Hendrick

All Master's Theses

This project investigated the movement and evolution of sediment clusters after four separate flood events at two geomorphically different sites along the Entiat River, Washington. Clusters are defined as an obstacle or anchor clast(s) that impede the progress of two or more sediment particles, and are believed to be an important characteristic of the variable bed topography of gravel-bed rivers. Detailed field descriptions and digital photographs of clusters were used to determine the characteristics of clusters at chosen locations on gravel bars regularly covered by high flow events. Data were collected during low-flow conditions, and clusters were re- examined and …


Runoff Production In The Upper Rio Chagres Watershed, Panama, Fred Ogden Dec 2004

Runoff Production In The Upper Rio Chagres Watershed, Panama, Fred Ogden

Fred L. Ogden

Runoff production in tropical watersheds is governed by a wide variety of potential sources and there have been few rigorous studies to date. The 414 km2 upper Río Chagres basin offers a unique opportunity to better understand the runoff production mechanisms in tropical watersheds through data analysis and modeling with rainfall and runoff data. Flow data and tipping bucket rain gage data are available at both the basin outlet (Chico gage) and for an 80.6 km2 internal basin location (Piedras gage). Modeling is performed using the Sacramento Soil Moisture Accounting Model (SAC-SMA), calibrated using data from 2000 and verified using …
