An embankment pond is made by building an embankment or dam across a stream or other natural watercourse where the stream valley is depressed enough to permit storing 5 feet or more of water.
damage the embankment and may stir up sediment from the reservoir floor. It is best, therefore, to provide a small wallowing/drinking pond downstream of the reservoir.
Upstream Slope Protection | Association of State Dam Safety
Without proper slope protection, a serious erosion problem known as “beaching” can develop on the upstream slope. The repeated action of waves upon a vegetated embankment surface over time may erode embankment material and deposit it farther down the slope, creating a “beach.”
Reservior & Farm Pond Design: Lesson 5 Earthen Embankments
Heel of Dam: The junction of the upstream face of a gravity or arch dam with the foundation surface is called heel of the dam. In the case of an embankment dam, this junction is referred to as the upstream toe of the dam.
Overview: Create the surface model and earthwork volumes for a pond embankment with a wave berm. A surveyed site with a surface model covering the footprint of the dam is needed. Final elevations of the normal pool, auxiliary spillway, and top of …
PNS/BAFS/PAES 226:2017 - Rainwater and Runoff Management
The water surface shall be kept clear of floating vegetation, except for a buffer strip 1m to 2 m wide to help reduce wave erosion of the upstream embankments. ________________ (kangkong) can be used as buffer strip. It forms an edible mat and …

Feb 1, 2023 · Erosion of upstream face: The waves developed near the top water surface due to wind action may erode the upstream face. The upstream face should be protected with stone pitching or riprap to avoid erosion.
relationship to an earlier embankment at the upstream toe. It has a 25-foot crest width and upstream slopes of 3 vertical to 1 horizontal (3:1) and downstream slopes between 3 and 4 vertical to 1 horizontal [4]. Approximately half of the downstream face of the embankment is submerged by the North Clear Pond.
Design a cutoff of relatively impervious material under the dam and up the abutments as required for preventing seepage. Locate the cutoff at, or upstream from, the centerline of the dam. Extend the cutoff deep enough to intercept flow and connect with a relatively impervious layer. Combine seepage control with the cutoff as needed.
In order to develop a surface that reflects the constructed storage, create an estimated upstream face of the dam. Tool Palette>NRCS 11x17B... Click Plan Commands... Embankment CL New. Draw a line that represents the centerline for the embankment. This alignment can have multiple vertices. It needs to be longer than the potential embankment.
