Question

Which type of the settlement shell be around a Pond?

Answer 1

Introduction

1. When the construction site has been prepared, the fish pond and its water control structures can be built. This chapter shows you how to construct the fish pond, while the next chapters of this manual, deal with water control structures.

2. Dikes are the most important part of a fish pond, as they keep the necessary volume of water impounded and form the actual pond; their design and construction is particularly important. You will learn more about pond dikes and earthwork calculations in the next three sections, before learning how to stake out and construct the four main types of pond.

3. You will find it useful to have a notebook in which to make any calculations required and, if available, some squared or graph paper for sketching out and measuring pond and dike shapes.

6.1 Characteristics of pond dikes

1. Any pond dike should have three basic qualities.

(a) It should be able to resist the water pressureresulting from the pond water depth.

(b) It should beimpervious, the water seepage through the dike being kept to a minimum.

(c) It should be high enough to keep the pond water from ever running over its top, which would rapidly destroy the dike.

Resisting water pressure

2. Water pressure can be readily resisted by:

anchoring your dike strongly to its foundations (the soil on which you build it);

constructing your dike large enough to resist the water pressure by virtue of its weight.

 

Answer 2

A compact type of settlement shell should be there around a pond.

Explanation:

• A pond ecosystem is in itself a small and sensitive ecosystem which can get disturbed by even the slightest of changes in the surrounding.

• Any major changes in the consumption of water from the pond or a change in the surrounding atmospheric pressure can lead to the entire ecosystem getting irrevocably disturbed.

• Thus, only the factors that favor the sustenance of the pond should be given access to the pond.

• To keep a pond ecosystem undisturbed, it is necessary that there is not much settlement around the pond.

• Hence, the settlement shell around a pond should be 'compact'.
