This is a multi-year project to repair a diversion structure which is preventing a head-cut from continuing upstream. Objectives: 1) Reduce or halt erosion occurring at the headcut. 2) Halt the headcut progression which may infringe on and destabilize upstream railroad, highway, interstate, and mine PMT. 3) Halt the headcut progression into the upstream channel morphology and riparian regime. Strategies: • Detailed runoff and flow analysis to the headcut location for the associated 830 square mile drainage area. • Selection of the acceptable design event/peak design flow for the structure. • Determination of all permitting requirements, timeframes, and responsibilities. • Evaluation of the native material stability...

The intense demand for river water in arid regions is resulting in widespread changes in riparian vegetation. We present a direct gradient method to predict the vegetation change resulting from a proposed upstream dam or diversion. Our method begins with the definition of vegetative cover types, based on a census of the existing vegetation in a set of 1 x 2 m plots. A hydraulic model determines the discharge necessary to inundate each plot. We use the hydrologic record, as defined by a flow duration curve, to determine the inundation duration for each plot. This allows us to position cover types along a gradient of inundation duration. A change in river management results in a new flow duration curve, which is used...

A water right is a legal right to use surface or ground water under the Alaska Water Use Act (AS 46.15).A water right allows a specific amount of water from a specific water source to be diverted, impounded,or withdrawn for a specific use. When a water right is granted, it becomes appurtenant to the land wherethe water is being used for as long as the water is used. If the land is sold, the water right transferswith the land to the new owner, unless the Department of Natural Resources (DNR) approves its separationfrom the land. In Alaska, because water wherever it naturally occurs is a common property resource, landownersdo not have automatic rights to ground water or surface water. For example, if a farmer has...
