# Moscow Environmental Database

A number of databases of preexisting data are provided with the package. These are provided to allow the user to start getting preliminary results quickly, prior to analysis of field erosion and runoff data for their specific site conditions (i.e. soils, climate). These databases are provided on cavaet empta basis and not intended to be used for defensible design calculations. The developers of the EAMS will not be held responsible for damages resulting directly or indorectly from their use.

## Using Existing Datasets in a Database

A EAMS database has extension .SDB (for SIBERIA DataBase). A number of default databases are provided as part of the install and are in the program directory. To open the database click on the menu item OPEN DATABASE in the PARAMETERS menu. To select the parameters you must then select a particular dataset from that database. To do this clickm on the menu item DATABASE RECORD. A dialog comes listing each dataset that is available within that database. The arrow buttons below the list can be used to navigate up and down through the list. Once you have found the dataset you want click on it once so it is highlighted, and then click on the RETRIEVE button. The parameters in this dataset can now be modicified with EDIT PARAMETERS menu option

## Creating New Datasets in a Database

Before you do this you should make a copy of one of the existing databases to your one of your own directories (because you won't be able to modofy any of the defailt databases) and rename it something descriptive. You will be using one of the existing datasets as a basis for your new datasets, and then when you have input all the new datasets you want you can then go back and delete all of the prior datasets that are in the database that you don't want.

1. Open the database you have just copied over to your home directory and retrieve a dataset that is similar to one you want to create.
2. Modify the parameters in this dataset to what you require. When you have done this click on the menu item DATABASE RECORD. Do not select a data set. Instead type in a new name (one that is not already in the database) and then click on the button SAVE. This parameter set is now saved in the file with the name you have then given it. You should find it at the end of the list of datasets if you scroll down through the list.

NOTE: If the database you have opened is in a write protected directory (e.g. typically the program directory, where the default databases are stored, is write protected though this will depend on how your commputer is set up), or if the database itself is write protected then the SAVE command will fail.

## Deleting Unwanted Datasets from a Database

Open the database with the menu item DATABASE RECORD. Select the data set you wish to delete and press the button DELETE. Note this deletion is permanent and cannot be undone, so delete carefully. If the database is write protected then this deletion will fail.
