- Formation of cracks due to anomalies in the coating material or associated with the substrate elements.
- The diagnosis needs to establish the causes of cracks and identify the existing topography as well as the degree of damage.
- The study indicates a strong dependence on the variations of surface temperature and sun incidence with no agreement about the criteria regarding the best time to make the thermographic inspection in day or night
- The use of thermography to study cracks, detachment, and humidity are still being performed on an experimental basis.
- Thermography is used to observe the location of cracks
- Nowadays, the weather conditions in the country where the studies are being performed are an important variable in the process and results since they involve differentiation of heat flux for each study.
How can we measure the infiltration rate in the filed? Mention the apparatus used for the measurement.
-
Generally, for measurement of infiltration on the field we use the Cylindrical Infiltrometer of diameter 30 cm and 60 cm. Basic infiltration rate for a different type of soil are as below: If the infiltration rate is 1-5 mm/hour that it is Clay. If the infiltration rate is 5-10 mm/hour that it is ClRead more

- If the infiltration rate is 1-5 mm/hour that it is Clay.
- If the infiltration rate is 5-10 mm/hour that it is Clay Loam.
- If the infiltration rate is 10-20 mm/hour that it is Loam.
- If the infiltration rate is 20-30 mm/hour that it is Sandy Loam.
- If the infiltration rate is greater than 30 mm/hour that it is Sand.
What is the criteria for the location of the head works in the irrigation system?
-
For deciding the location of headwork an irrigation system, you should have to follow points during the selection of location. Elevation of water should be in such a manner that the water will flow under the gravity force. All the construction materials should be available in the surrounding area. DRead more
For deciding the location of headwork an irrigation system, you should have to follow points during the selection of location.
- Elevation of water should be in such a manner that the water will flow under the gravity force.
- All the construction materials should be available in the surrounding area.
- Diversion head should be near the irrigation for irrigating area as possible and for keeping minimum canal length.
What are the methods used to control silt at head work?
-
The following ways can help to remove or control silt at head work. 1. By installing silt excluder you can control or remove silt easily. 2. Provide a divide wall at the side of canal in river to create trap or pocket for controlling silt. 3. By making smooth flow we should have to avoid unsteady flRead more

The curve number method is an adaptable and widely used for runoff estimation. This method is important properties of the watershed, specifically soil permeability, land use and antecedent soil water conditions which take into consideration.

The curve number method is an adaptable and widely used for runoff estimation. This method is important properties of the watershed, specifically soil permeability, land use and antecedent soil water conditions which take into consideration. Thus, straightforward methods of calculating runoff can tell you the amount of water that storms bring to the earth. For a given surface area such as a roof or yard, multiply the area by the inches of rainfall and divide by 231 to obtain the runoff in gallons.

What is contour farming?In which type of soil contour farming is suitable?
-
Contour farming is an agricultural practice where steps are cut out on a sloped field so as to provide steps of flat land (same contour) for cultivation. The potential benefits are a check on erosion, better rainfall usage, more infiltration, and reduction in the need for irrigation. It is feasibleRead more
Contour farming is an agricultural practice where steps are cut out on a sloped field so as to provide steps of flat land (same contour) for cultivation. The potential benefits are a check on erosion, better rainfall usage, more infiltration, and reduction in the need for irrigation.
It is feasible on all slopy regions to accept on those with highly erodible soils and soils that allow little infiltration.
