Assignment 6

Part 1 Questions: For NM963

1) How many components does it have? It has 5 soil components.

2) What are there names? REGNIER, LATOM, ROCK OUTCROPS, LOS TANOS, GALLEN

3) What percentage of the map unit does each component comprise?

REGNIER = 36%

LATOM = 32%

ROCK OUTCROPS = 18%

LOS TANOS = 12%

GALLEN = 2%

4) What is the predominant surface slope where the map unit is found? Done by those with highest percentage.

ROCK OUTCROP: 0-99

REGNIER: 3-15

LOS TANOS: 0-5

LATOM:5-15

GALLEN: 5-35

5) What is the dominant soil texture?

ROCK OUTCROP: UWB

REGNIER: C (Clay) L (Loam), GR (Gravel)-S (Sand) C (Clay) L (Loam)

LOS TANOS: F (Fine) S (Sand) L (Loam)

LATOM: F (Fine) S (Sand) L (Loam), GR (Gravel) - F (Fine) S (Sand) L (Loam)

GALLEN: GR (Gravel) –S (Sand) L (Loam)

6) What percentage of the soil is in hydrologic soil groups A, B, C, D?

A = 0%

B = 2%

C = 12%

D = 86%

7) Do these soil properties make sense considering where the soil is located? Yes, they are what would be expected near a river. In my experience floodplains typically have sands, clays, and gravels.

Part 2 Questions: For Mapunit NM963

1) How many layers does each component have?

Comp 1 = 3 (Regnier)

Comp 2 = 2 (Latom)

Comp 3 = 1 (Regnier)

Comp 4 = 3 (Los Tanos)

Comp 5 = 3 (Regnier)

Comp 6 = 2 (Latom)

Comp 7 = 3 (Regnier)

Comp 8 = 4 (Gallen)

2) What is the total soil depth (inches) for each layer and the average depth (inches) for the map unit?

Total Soil Depth Mean Depth (comppct/100)*component depth

Comp 1 = 22 Comp 1 = (27/100) 22 = 5.94

Comp 2 = 20 Comp 2 = (27/100) 20 = 5.4

Comp 3 = 60 Comp 3 = (18/100) 60 = 10.8

Comp 4 = 28 Comp 4 = (12/100) 28 = 3.36

Comp 5 = 22 Comp 5 = (7/100) 22 = 1.54

Comp 6 = 20 Comp 6 = (5/100) 20 = 1.0

Comp 7 = 22 Comp 7 = (2/100) 22 = 0.44

Comp 8 = 60 Comp 8 = (2/100) 60 = 1.2

Mean = 3.71 inches

3) What is the total water holding capacity (inches of water) over the full soil depth for each component?

Available Water Capacity = (awcl + awch)/2

Comp 1: REGNIER = 3.06/18 in. soil

Comp 2: LATOM = 1.0/8 in. soil

Comp 3: ROCK OUT CROP = 0.0

Comp 4: LOS TANOS = 3.3/24 in. soil

Comp 5: REGNIER = 3.06./18 in. soil

Comp 6: LATOM = 1/8 in. soil

Comp 7: REGNIER = 2.43/ 18 in. soil

Comp 8: GALLEN = 3.52/60 in. soil

4) What is the average water holding capacity (inches of water) for soils in this map unit?

The mean water holding capacity is 2.17 in. of water.

I had no real problem with this portion of the assignment.

Part 2: Land use projections.

Soil Map

I have provided the Soil Map of the Pecos. It illustrates the diversity of soil types in the region. Also, I had problems projecting this layer on the map below and wanted to include it here to show the Pecos region highlighted. It was supposed to be shown on the map below but I could not get it t work. This was just one of the problems I had with the portion of the assignment.

This is the Land Use map of the Fort Sumner and Sante Fe data obtained from the rgis website. This was a frustrating exercise in futility! My problems began when I originally downloaded the data. There were data errors the first three times I downloaded the data and it kept making to program crash for no apparent reason. The fourth time it worked and the program no longer shut down.

I could not append the files. Again, when I tried this the program would suddenly shut down and give me an error report. I am not sure, but I think this may have affected my scale bar because I could not add it in a way that makes sense in regards to the map and the area covered. This particular assignment was very frustrating because of all of the glitches I encountered. I would like the opportunity to try and complete the project properly so that I don’t lose the points for what I was unable to do correctly.
