Q & A

What is the primary function of a water reservoir (embung)?

The primary function of a water reservoir is to capture and manage rainwater for various uses such as agriculture, livestock, and flood control.

How is the location of a reservoir determined?

The location is determined by selecting an area with appropriate elevation that allows rainwater to naturally flow into the reservoir through gravity.

What are the key components of a small reservoir?

Key components include an inlet for water entry, a sedimentation basin, a distribution system, and outlets for irrigation or household use.

What role does community involvement play in reservoir maintenance?

Community involvement is crucial as it ensures the sustainability and proper maintenance of the reservoir, fostering a sense of responsibility among local users.

What are the benefits of using remote sensing in reservoir planning?

Remote sensing helps identify the highest points for reservoir locations and assesses rainfall patterns, making the planning process more efficient.

What regulations govern the construction of reservoirs in Indonesia?

Key regulations include the Minister of Public Works and Public Housing's guidelines on small reservoirs and various technical directives on reservoir development.

What are the classifications of reservoirs based on height?

Reservoirs are classified into categories based on their height: those under 3 meters, between 3 and 10 meters, and those over 10 meters.

What methods are recommended for calculating flood risks related to reservoir planning?

Recommended methods include hydrological unit hydrographs and rational methods for estimating peak flood flows.

How do geomembranes enhance reservoir functionality?

Geomembranes prevent water loss due to seepage and improve structural stability by accommodating soil movement, thus enhancing reservoir efficiency.

What are the environmental impacts of poorly maintained reservoirs?

Poorly maintained reservoirs can lead to erosion, sediment buildup, and compromised structural integrity, ultimately reducing their effectiveness and posing safety risks.
